I was thinking along the same lines a while ago, in an attempt to find a lighter camera than my Technika III.

Unlike most landscape photographers, I find that I really need front swing as well as tilt, shift and rise. So that simplified things a bit for me...

My top candidate was Ebony, as the only one which could accomodate my massive 300mm/f:4.5 Xenar lens.
Next on my list are Lotus, Gandolfi and Shen-Hao.

But I decided to stick with my Technika, and rather look into 8x10" when I can afford a new camera
